示例1: visitInvokeInst
// visitInvokeInst - Converting the "invoke" instruction is fairly
// straight-forward. The old exception part is replaced by a query asking
// if this is a longjmp exception. If it is, then it goes to the longjmp
// exception blocks. Otherwise, control is passed the old exception.
void LowerSetJmp::visitInvokeInst(InvokeInst& II)
{
if (II.getCalledFunction())
if (!IsTransformableFunction(II.getCalledFunction()->getName()) ||
II.getCalledFunction()->isIntrinsic()) return;
BasicBlock* BB = II.getParent();
// If not reachable from a setjmp call, don't transform.
if (!DFSBlocks.count(BB)) return;
BasicBlock* ExceptBB = II.getUnwindDest();
Function* Func = BB->getParent();
BasicBlock* NewExceptBB = BasicBlock::Create("InvokeExcept", Func);
BasicBlock::InstListType& InstList = NewExceptBB->getInstList();
// If this is a longjmp exception, then branch to the preliminary BB of
// the longjmp exception handling. Otherwise, go to the old exception.
CallInst* IsLJExcept = CallInst::Create(IsLJException, "IsLJExcept");
InstList.push_back(IsLJExcept);
BranchInst::Create(PrelimBBMap[Func], ExceptBB, IsLJExcept, NewExceptBB);
II.setUnwindDest(NewExceptBB);
